[artist id="1933910"]Carrie Underwood[/artist] is taking her act from the small screen to the big screen. The country-music superstar has been cast in a supporting role in the movie "Soul Surfer." Filming begins this month.

Underwood, who picked up a Grammy for Best Country Collaboration (with Randy Travis) and was one of the stars featured in the Michael Jackson tribute at Sunday's Grammy Awards, will play church youth leader Sarah Hill. The movie is based on the real-life story of Bethany Hamilton, the 19-year-old champion surfer who lost her arm in a shark attack at the age of 13, but has managed to continue competing and winning professional championships.

Underwood will star alongside Helen Hunt, Dennis Quaid, Kevin Sorbo and AnnaSophia Robb, who is tapped to play Bethany Hamilton. But before she begins filming, Underwood will be on hand this weekend to perform the national anthem for Sunday's Super Bowl XLIV, which pits the Indianapolis Colts against the New Orleans Saints in Miami.

The onetime "American Idol," who recently became engaged to hockey superstar Mike Fisher, has been stretching her acting muscle. She just shot a cameo for the show "How I Met Your Mother," which is set to air in March. In it she plays a pharmaceutical sales rep and love interest for the show's male lead, Ted (Josh Radnor). "I'm giving up the music business and I'm going to become a professional sitcom actress!" she wrote about her acting debut. "Just kidding, of course, but I did have a blast while I was there!"

Also starting in March, Underwood will hit the road for her Play On tour. "I am getting so excited. ... I cannot wait to perform new music and see familiar faces across the U.S. and Canada!" Underwood said in a statement.
